vices, of which the following is a speciication, reference being hadtherein to the accompanying drawing.

This invention relates to new and useful improvements in tire nutturning devices.

My invention comprises various details of construction, combination andarrangement of parts which will be hereinafter fully described, shown inthe accompanying drawings and then specifically defined in the appendedclaim.

My invention is illustrated in the accompanying drawings which, with theletters of reference marked thereon, form a part of this application,and in which: y

Figure 1 is a side elevation of the apparatus, parts being in section.

Fig. 2 is an enlarged detail Sectional view through a part of theapparatus.

Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Reference now being had to the details of the drawings by letter:

A designates the frame of the machine, in which a reversely spiraledshaft `D is mounted in suitable bearings. A gear wheel E is keyed torotate with said shaft, and D is a bumper mounted upon the4 shaftadjacent tosaid wheel. Mounted in a cylindrical bearing B in a laterallyextending portion B of the frame is a socket member H, which carries ayspring pressed socket member H" adapted to engage a nut to be tightenedindicated at Z. A coiled spring H2 is mounted within the socket memberH, the tension of y which is regulated by a screw H3 mounted in thelower threaded end of the socket member. A gear wheel E is fixed to saidsocket member H and is in mesh with the gear E carried upon the shaft D.

Said shaft D has reversely'spiraled grooves K, whichv are provided forthe purpose ofh giving the shaft a rotary movement through the medium ofa mechanism, which will be presently described, a hand wheel D2 beingalso provided for the purpose of applying rotary motion directly to theshaft.

Mounted to have a reciprocating movement upon the shaft D is a sleeve N,detail f of which is shown in Figs. 2 and 3 of the drawings, and withinwhich are mounted two cylindrical ratchets P andQ, the former being aright hand-.ratchet and the latter a lefthand ratchet, andeach hasoppositely inclined lugs P and Q" respectively, which slide in thespiral grooves at kpoints diametrically opposite;

A rock shaft O is journaled in suitable i bearings within the sleeve andhas pawls R and S fixed thereto, designed to engage respectively thereversely arranged ratchets, and reversing bars J are held tothe rockshaft means of set screws J, and are provided with lugs J2 which,bearing against the pawls R land S, afford means whereby the shaft O maybe turned in one direction or the other, according as it may be desiredtol throw one or the other of the-pawls into engagement with one or theother of said ratchets. Pivotally mounted upon a stud R is a lever R2having a slot T in oneedge thereof designed to engage an anti-frictionroller T mounted upon a bar T2, which is carried by the sleeve N, andserves as a means for lmoving the same, as the lever is swung upon itspivot R for the purpose of rotating the shaft in one direction or theother. Suitable ratchet springs X upon the shaft O bear against thepawls to hold the same yieldingly in engaging positions.

In order to guide.' the housing as it reciprocates, a suitable arm Y iscarried thereby,

and has a bifurcated end which slides upon the bar M which is spaced inparallelism` with the shaft D. Pivotally mounted upon a pin W, upon thebar V3, is a lever W carrying a screw W2 mounted in a threaded aper- Iture in the lever and has its lower end terminating in points adaptedto' frictionally en-` gage the end of a boltz V held inthe rim V of awheel. Said lever has an integral lug W4 projecting therefrom, which isadapted to be engaged by a springcatch W3 when the lever is in theraised position shown in dotted lines in Fig. 1 of the drawings.

A bracket arm V2 is fastened by means of a bolt VX to said, bar V3. Theouter end of said arm is fastened to the frame by means of a bolt B3.

In operation, a ratchet pawl is adjusted to cause one or 'another of theratchets to be Y rotated in, one direction, whereupon, by theoscillation of the lever R2 upon its pivot R', sliding the sleeve Nalternately upwardly and downwardly upon the shaft D,.step by steprotary motion is imparted to said shaft. 3

By the reversal of the member J reversing the pavvls R and S, thedirection of rotation y of the shaft D is also reversed, so that thedevice is adapted for either screwing or unserewing nuts and to rotatethe gears in eitherdirection and through the gear connections with thewrench socket member.

l/Vhat I claim to be new is:

The combination with a frame embodying spaced vertical journal bearings,of a shaft reversely spiraled journaled in the bearings, operating meansslidable upon the shaft, bars rigidly secured to the frame upon oppositesides of and in parallelism with the shaft, means engaging one of saidbars for holding the operating mechanismk against rol tation, an oi'lsetrigidly connected with the other bar and provided with a seat, a Wrench,member mounted to rotate in the seat, means the lever, provided with aplurality of engaging points, a lever adapted to actuate the operatingmeans, and an additional mean for applying power to the shaft.

ln testimony whereof I hereunto aiiX my signature in presence lof twowitnesses.
